Motor rotor assembly

Abstract

The invention discloses a motor rotor assembly, comprising a rotor cylinder, rotor cores, a rotating shaft and a connection protecting mechanism; the rotor cores are spaced apart from the outer side wall of the rotor cylinder, the rotating shaft extends vertically into the middle portion of the inner cavity of the rotor cylinder, the connection protecting mechanism is mirror-arranged and fixedly connected to the end of the rotor cylinder, and the connection protecting mechanism is fixedly connected to a joint between the rotor cylinder and the rotating shaft. According to the motor rotor assembly, a reinforcing protection structure can be formed at the joint between the rotating shaft and the rotor cylinder, so that the rotating shaft and the rotor cylinder are always firmly integrated, thereby preventing the rotating shaft from being separated from the rotor cylinder during use to affect the normal use of the motor rotor assembly, and simultaneously enclosure protection is carried outon the joint between the rotating shaft and the rotor cylinder, thereby reducing the probability of breakage and fracture at the joint between the rotating shaft and the top of the rotor cylinder when the motor rotor assembly is in use.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor rotor assembly. Background technique [0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The rotor assembly is a part of the motor. With the continuous development of science and technology, different types of motor rotor assemblies have appeared in the market. The motor rotor assembly includes rotor columns. Body, rotor core and shaft. [0003] However, in the current motor rotor assembly on the market, when the motor rotor assembly is used for a long time, it is prone to the problem that the shaft and the rotor cylinder are separated, causing the problem of breaking and cracking at the connection between the shaft and the top of the rotor cylinder, which affects the normal operation of the motor rotor assembly. Use, is unfavorable for popularizing and us...
